Brief Summary

Ultrasound-guided Modified Thoracoabdominal Nerve Plane Block (M-TAPA) is performed deep into the costochondral aspect at the 9th-10th costal level by injecting local anesthetics deep into the chondrium. It provides blockage of both the anterior and lateral cutaneous branches of the thoracoabdominal nerve. As there are studies showing M-TAPA block to be effective for postoperative analgesia for other abdominal surgeries, its effect on patients undergoing living liver donor surgery has not been studied yet. We hypothesize that M-TAPA block performed in living liver donors would reduce opioid consumption in the first 48 hours after surgery.

Outcome Measures

Primary Outcomes (1)

  • Opioid consumption (Fentanyl PCA)

    The primary aim is to compare postoperative opioid consumption from the PCA device.

    Changes from baseline opioid consumption at postoperative 1, 2, 4, 8, 16, 24 and 48 hours

Secondary Outcomes (3)

  • Pain scores (Numerical rating scale-NRS

    Changes from baseline pain scores at postoperative 1, 2, 4, 8, 16, 24 and 48 hours]

  • Need for rescue analgesia (meperidine)

    Postoperative 48 hours period

  • Adverse events

    Postoperative 48 hours period

Study Arms (2)

Group A=M-TAPA block group

EXPERIMENTAL

M-TAPA plane block will be performed and standard postoperative pain management protocols will be applied.

Procedure: M-TAPA plane blockProcedure: Postoperative pain management

Group B = control group

ACTIVE COMPARATOR

Only standard postoperative pain management protocols will be applied. No plane blocks will be applied

Procedure: Postoperative pain management

Interventions

As the patient is in the supine position, the high-frequency linear US probe (11-12 MHz, Vivid Q) and a 22-G 80-mm needle (Pajunk Sonoplex Nanoline Stim Cannula, Germany) will be placed in a sagittal position at the costochondral junction at the level of the 9th and 10th ribs. After the rib and the external oblique, internal oblique, and transversus abdominis muscles are visualized on USG, using an in-plane technique, the block needle will be advanced and the block location will be confirmed by injecting 5 ml of saline between the internal oblique and transversus abdominis muscles. Once the block location is confirmed, 30 ml of 0.25% bupivacaine (Buvicaine ®) will be applied bilaterally (60 ml in total).

Group A=M-TAPA block group

For preemptive analgesia, morphine (Morfin ®) 0.05mg/kg and Ibuprofen 400mg IV (Ibuprofen®) will be administered to all patients before the surgical incision. An additional dose of ibuprofen 400mg IV, meperidine (Aldolan ®), and tramadol (Contramal®) 1mg/kg IV will be administered to all patients 30 minutes before wound closure.10 mcg/ml fentanyl containing PCA will be connected to all patients without infusion and boluses 0,35 mcg/kg,15-minute lockout period, maximum 100 mcg per hour. Postoperative patient evaluation will be performed by another anesthesiologist. If the NRS score is ≥ 4, 0.5 mg/kg IV meperidine (Aldolan®)will be administered as a rescue analgesic.
